Things escalated from there, as Gracie’s group allegedly squared off with a group of 1-Oak bouncers.

No word on how many bouncers there where but the term group typically means more than one.
No doubt that they still had them out numbered.

Of the single rapier fight between valiant men, having both skill, he that is the best wrestler, or if neither of them can wrestle, the strongest man most commonly kills the other, or leaves him at his mercy.
